Ethyl Methacrylate Monomer
Pure ethyl methacrylate (CH2=C(CH3)COOCH2CH3) is a colorless liquid unsaturated acyclic monocarboxylic acid ester used primarily as a monomer in polymerization reactions. It falls under HTS 2916.14.2010 as a specific ester of methacrylic acid, chemically defined per Chapter 29 note (a). Stabilizers may be added for safety and transport without changing classification.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If contains >5% impurities or polymerization inhibitors
Mixtures of organic chemicals not chemically defined fall under Chapter 38 prepared binders, not pure Chapter 29 compounds.
If pre-polymerized into acrylic resin solution
Polymerized acrylic polymers in solution classify under Chapter 32 paints/varnishes, not monomer esters.
If sold as mixture of C2-C14 acyclic alcohols
Alcohol components separated from acid functionality classify under Chapter 29 alcohols, not acid esters.

Import Tips & Compliance
• 1
• Provide Certificate of Analysis confirming ≥98% purity as ethyl methacrylate to avoid reclassification; 2
• Include stabilizer disclosure (e.g
• MEHQ <0.01%) per Chapter 29 note (f); 3
• Ship in UN-approved drums due to polymerization hazard, avoiding bulk tankers
